I realise caricatures are generally quite unflattering, but this seems to be quite poisonous for no apparent reason! The artist was Georges Goursat (Sem) and the piece appeared in Le grand monde à l’envers in 1919. The caption reads:
Mam’selle Coco j’voudrais un beau chapeau pour le Dimanche
Which, if my schoolgirl French suffices, translates as ‘Miss Coco, I would like a beautiful hat for Sunday’. So, why Coco Chanel is portrayed as a sour-faced hunchback I have no idea! Am I missing something?
